Hi folks,
I just upgraded from a 2gig 4890 to a 6870 this morning. Installed and working fine but I'm having a problem connecting all three of my LCD monitors and so have some questions about port connectivity with this card.
Where the card comes with a DL-DVI port, a DVI port, an HDMI and 2 mini-displayports, I have two monitors connected right now:
I picked up a DVI to mini-displayport adapter for monitor 2 and plugged it into the 1st mini displayport. It works fine at the native 1920x1080 and looks good.
I have my main monitor (1) hooked up as DVI to DVI. It runs correctly at its native 1920x1200 and looks good.
The problem is monitor 3, or the one on the left. This is a Samsung 2233sw with DVI and VGA output ports. I currently have it connected via a VGA cable into a VGA mini displayport adapter into the 2nd mini-displayport on the video card. While it's working, it only runs at 1600x1200. It refuses to display at the monitor's native 1920x1080 and it looks pretty bad. I've tried reinstalling the monitor driver, letting W7 pick its own and so forth. No matter what I do it won't let me select the optimum resolution of 1920x1080. I'm wondering why not. My understanding is a VGA cable can support 1920x1080 (and above), but is it possibly not jiving well with the mini-dp adapter? I can connect it using a DVI to DVI cable in the second DVI slot but it seems the radeon 6870 won't let you use both DVI ports at the same time and W7 won't even find the monitor that way. There's an HDMI slot free on the video card but I'd need a DVI to HDMI cable for that and I don't know if that will support 1920x1080.
So, I'm stumped. Any ideas? Headed to a cable store on Monday so hopefully will have the right answer on what the best buy (ha) is to get the right resolution. Thanks in advance to anyone with appropriate info.
